Bad noises while revving
Alright so I'll make this quick....
When I start to rev the engine it starts squealing... really loud! Any idea on what's going on? |

loose power steering or ac belt..
alternatively seized timing/balance belt roller or worst case, seizing water pump pulley. |

If the Belts are loose they can be tightened with the turnbuckles. which will not cost you anything. Belts do not cost a lot, but the pulleys can cost a bit. Can you push on the Alternator or Power steering belt to see if they move a lot? The loud Squealing could be from the Alternator if the Belt is not tight enough. Hope this helps out.

Be careful with the turnbuckles, if turned without loosening the end bolts and the pivots the turnbuckles will (at best) break, or break the ears on the AC or PS. At worst they will shear ears off the block. They have so much leverage you cannot really feel that you are breaking stuff.
It's easy to break this stuff and drive away unknowingly only to have the AC pump fall off down the road a few hundred miles.

A seizing water pump can break the timing belt and then you are looking at a LOT more $$$'s. An over tightened balance shaft belt will also cause the squealing noise. What has happened with the car recently.
